I looked into the RX III and while it seems like a great camera, I'm hesitant as it offers no lens switching options. I'm thinking that may be a gift avenue for her down the road.
I also stumbled onto this: http://www.tomsguide.com/us/camera-buyi ... 17666.html and it seems to suggest the big advantage with mirrorless is the compactness. Is there such a thing as an SLR with a general lens for 90% of stuff, and then maybe for special trips she can take a bag with an extra lens?
I'm going to go back and read some more.
